IMPROVEMENT IN LOCKING DEVICES FOR THE TABLES 0F CHILDRENS CHAIRS.

Specification forming part of Letters Patent No. 222,001, dated November25, 1879; application filed July 21, 1879.

To all whom it may concerns Be it known that I, NICHOLAS BARTELL, of thecity of Milwaukee, in the county of Milwaukee and State of Wisconsin,have invented certain new and useful Improvements in Looking Devices forTables of Childrens Chairs; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and toletters of reference marked thereon, which form apart of thisspecification.

My invention relates to improvements in that class of chairs which areprovided with a swinging table attached 'to the front ends of theirarms, which table serves to retain the child in the seat, as well as fora receptacle for toys, &c.

My invention consists more especially in the locking device by which oneend of said table is temporarily attached to one of the chair-arms, ashereinafter set forth, the other end of said table being hinged orpivoted to the other arm in the ordinary manner, all of which is furtherexplained by reference to the accompanying drawings, in which- Figure 1represents a side view of my invention. Fig. 2 is a bottom view of thesame. Fig. 3 is an end sectional view. Fig. 4 is a side sectional view.Fig. 5 is a perspective view of the staple which is driven into thelower side of the swinging table.

Like parts are indicated by the same reference-letters.

A represents the arm of the chair, to which my lockin g device isattached. B is the swinging table. G is a staple, which is constructedin the peculiar shape shown in Fig. 5, having angles a, Z), c, (I, e,and f. I

The staple O is driven into the lower side of the table until that partof the staple between a. and b and e and f bears against its surface,thus serving as a brace to sustain the staple in a rigid verticalposition.

D is a catch which is secured to the chairarm A within the slot E. Theslot E maybe quickly formed with a saw of the required thickness by asingle cut.

The catch D is retained in the slot by pin F, which is driven throughthe arm passing through a hole in the back end of the catch, upon whichpin the catch freely turns as the front end of the catch moves upwardand downward.

Gr is a recess for the reception of the spiral spring H, which springacts against the catch D.

I is a projecting shoulder, which enters the coil of the spring, andserves. to retain it in its proper position against the catch.

J is a small staple, which is driven into the arm beneaththe catch,which it supports and retains in the slot.

The staple C may be made of. wire, which is readily bent in the peculiarshape shown. It is made wider than the end of the arm A, that thewarping or spreading of the arms of the chair will not prevent said armA entering and the said device being brought into locking position. I

The table Bis locked by the catch D, which engages with the staple Oautomatically when the table is brought into the position shown. Whendesirous-to throw back the table B the catch D is raised, so that thestaple escapes from beneath it.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-- 1. In devices for locki n g the swingingtables of childrens chairs, the combination of the herein-describedstaple G, having angles a, l), 0,01, 0, and f, with table B and catch D,all substantially as and for the purpose specified.

2. In devices for lockin g the swinging tables for. childrens chairs,the combination of the spiral spring H, catch D, as secured in slot E bypin F and staple J, with the staple (3, as secured to table B, allsubstantially as and for the purpose specified.

In testimony that I claim the foregoing I have hereunto, set my hand.

NICHOLAS BARTELL.
